The cap is G-18 lines broad, the stem is 1-3 inches lonj^, 2-4 

 lines thick. . It is gregarious and appeai-s from Julv to Sep- 

 tember. As an edible mushroom it is not ns lender as some nor 

 as highly ilavored, but it is satisfactory and enjoyable. 



It is related so closely to (' a n t har e 1 1 u s umbonatus 

 that it has sometimes been regarded as a variety of i1 or has even 

 been confused with it, but the gills of that species jire described 

 as straight, and in our plant Ihey are constantly repeatedly 

 forked asinC. aurantiacus and C. albidus. The umbo 

 in our plant is small and pointed and often wholly wanting, but 

 in C. umbonatus it is represented as broad and blunt. Be- 

 cause of these discrepancies it seems best to keep our plant 



distinct.

PLANTS OF THE SUSQUEHANNA VALLEY AND 

 ADJACENT HILLS OF TIOGA COUNTY 



BY FRANK E. FENNO 



The territory included in this flora consists of a strip of land 



about 8 miles wide, lying on both sides of the Susquehanna river 



and extending nearly east and west through the county. Its 



surface is broken by the foothills of the Alleghany mountains. 



These consist of a series of ridges from 1200 to 1500 feet above 



tide. They are divided diagonally by the valley of the Susque- 



.hanna and separated laterally by the yalleys of the Apalachin. 



Wapasening, Owego, Catatonk, Pipe and Cayuta creeks. Those 



creeks have rapid currents. Their valleys are narrow in the 



upper part, but expand toward the river into broad and level 



fields. 



The Susquehanna winds its way through a tortuous valley 



bordered on either side by banks, which generally slope grad- 

 ually to the broad and rolling hilltoj)s. Yet the valley is defined 

 in some places by steep and rocky acclivities which rise from 

 300 to 400 feet above the surface of the river. These acclivi- 

 ties furnish congenial homes for many rock-loving species of 

 plants. The soil in the valleys is mainly alluvial, lying on a deep 

 drift consisting of sand, gravel and clay. This drift forms the 

 c5oil of the adjacent hills. The territory contains yery little
